Re: What Are Lubricants Used For

I would like to tell you about that, What Are Lubricants Used for machines, as you want.

Here I am giving you information about it, as you want.


Lubricant;

A lubricant is a substance introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move.

It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.

The property of reducing friction is known as lubricity.

In addition to industrial applications, lubricants are used for many other purposes.

Other uses include cooking (oils and fats in use in frying pans, in baking to prevent food sticking),
Bio-medical applications on humans (e.g. Lubricants for artificial joints),
Ultrasound examination,
Medical examinations, and the use of personal lubricant for sexual purposes.


Properties
A good lubricant generally possesses the following characteristics:
High boiling point and low freezing point (in order to stay liquid within a wide range of temperature)
High viscosity index
Thermal stability
Hydraulic stability
Demulsibility
Corrosion prevention
High resistance to oxidation


Additives
Main article: Oil additive
Antioxidants
Detergents
Anti-wear
Metal deactivators
Corrosion inhibitors, Rust inhibitors
Friction modifiers
Extreme Pressure
Anti-foaming agents
Viscosity index improvers
Demulsifying/Emulsifying
Stickiness improver, provide adhesive property towards tool surface (in metalworking)
Complexing agent (in case of greases)

Types of lubricants
Base oil groups
Biolubricants made from vegetable oils and other renewable sources



Synthetic oils

Polyalpha-olefin (PAO)
Synthetic esters
